An Indian man who claims divine inspiration says he has survived 68 years without eating, drinking or relieving himself, baffling doctors who are unable to prove him an imposter. Prahlad Jani, a 76-year-old whose extraordinary tale has won him a small band of devotees, took a dare and underwent round-the-clock surveillance at a hospital in Ahmedabad (news - web sites), the commercial capital of the western state of Gujarat. "He has evidence of the formation of urine, which was reabsorbed on his bladder wall. The medical committee does not have any scientific explanation," Shah said.
